How to Measure Hard Water

Hard water is an inconvenience for homeowners and business owners. It can damage equipment, stain clothing, make water taste funny, discolor showers, leave spots on dishware, and more. Where does hard water come from, and can it possibly be measured?

Where Hard Water Comes From

As water rushes through riverbeds or gathers underground, it naturally collects minerals from the rocks it comes in contact with. These minerals, including limestone and chalk, are what makes a water “hard.” Limestone is made up of calcium and magnesium, and these are the elements that cause that film on your glass shower door or turn your delicate whites yellow in the washer.

Is It Possible to Measure Hard Water?

Limestone (calcium carbonate) is the prime mineral found in hard water, and it is indeed possible to measure calcium carbonate. The Pathfinder MCM-300 Mineral Content Meter measures the electrical conductivity of water to determine the amount of calcium carbonate within it. This can give you a good idea of how hard or soft the water is from a specific water source.
